Ultrasound Tomography Based Two-Phase Composition Measurement

Abstract

Reliable flow measurement at the surface is critical for production optimization and reservoir management. Commercial water-cut and three phase flow meters have limitations in accuracy over the range of multiphase flow conditions. They require frequent calibration, and have high capital and operational cost. This paper describes an ultrasonic tomography based measurement of water hold-up, and presents preliminary flow loop and field test results. This ultrasonic system has the potential to overcome certain limitations of existing metering solutions.
